IMPROVED HdRSESHOE-MACHINE.

Specification forming part of Letters Patent No. 56,280. dated July 10, 1866.

To all whom it may concern:

Be it known that we, JACOB SHINNELLER and JOHN BRISLIN, of Temperanceville, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Horseshoe-Machines; and we do hereby declare that the following is a full and exact description thereof, reference being bad to the accompanying drawings, and to the letters of reference marked thereon.

The nature of our invention consists in the use of a revolving disk provided with a die and clamp, and a lever furnished with swaging vof the same with the parts to the right of the dotted lines 15 removed, and represents the position of the disk and its die and clamp, and

also the position of the feeding'guide when the iron is placed in the machine prior to its being bent into the form of a horseshoe. Fig. 3 represents a similar view to that shown in Fig. 2, but represents the position of the disk and its die and clamp, and also the position of the feeding-guide after the iron is bent into the form of a horseshoe. Fig. 4 represents a side view of the disk and spring used for holdin g the shaft D and the parts attached thereto until the other parts of the machine have performed their office. Fig. 5 represents a face view, in outline, of the wheels at and n. Fig. 6 represents a perspective view of the lever g with the swaging-die and the cutter attached thereto. Fig. 7 represents a perspective view of the cam used for the purpose of operating the lever g.

In the drawings, A represents the base of the machine. B represents the head-block, in which is placed the revolving disk 10, to which the die 8 and clamp y are attached.

The feedingguide lis pivoted at 3 to the head-block B, and the adjustable guide J is arranged on and secured to it by set-screws l.

The shaft O has its bearings in the supports cf and head-block B, and is provided with a driving-pulley 1', gear-wheel n, cams k and 2' It will be observed that the shaft 0 passes through an opening, 10, in the lever g.

The shaft-D has its bearings in the headblock B and the support 0, and is provided with disks to and o, and with a gear-wheel, m. which gears into the wheel a on shaft 0.

The lever g is pivoted in the base A of the machine at the point marked 3, and is made in the form represented in Fig. 6, and armed with a swagingdie, 8, which is provided with punches for making the holes in the shoe and a flange or rim for surrounding the outer edge of the shoe. This flange or rim is used for the purpose of preventing the punches from burst ing or spreading the iron, the die with its punches and flange or rim being so constructed and arranged that the flange or rim will pass over and around the outer edge of the shoe at the same time the punches enter the iron of the shoe-that is to say, when the die 8 is forced upon the shoe by means of the cam 43 and lover g the flange of the (lie 8 will pass over the outside of the shoe as the punches of the die 8 enter the iron of the shoe, and will thereby prevent the punches from spreading or bursting the iron of the shoe.

The die 8 is provided with apress-tool, marked 4, which is furnished with a shank, marked 5, which passes through the die 8 and lever g, as shown in Figs. 1 and 6. To the die 8 is secured a cutter, marked 6, which is used for the purpose of euttin g off the shoe after it is formed around the die 8.

The die Sis secured to the lever g by a dovetailjoint, as shown in Figs. 1 and 6, or it may be secured to said lever by any other known and suitable means.

The lever g is moved forward by means of the cam i, which is made in the form represented in Fig. 7, and is moved or thrown back by means of the spring marked it, which is secured to the base Aof the machine; but other suitable device may be substituted for the spring h for operating the lever in its backward motion.

15 represents a side guide for the lever g, and is used for the purpose of preventing any side motion of said lever.

The feeding-guide lis provided with a friction-roller, marked as. and is operated by means of the cam 7c and the spring u, which is secured to the base A of the machine.

The disk 0 on shaft D is furnished with a notch, to which is fitted a catch made on the upper end of the spring 12, as shown in Fig. 4. This disk 0 and spring p are used for the purpose of holding the shaft D and the several parts attached thereto in a fixed position until the shoe which has been formed or bent around the die 8 is cut off, swaged, and punched.

The form in outline of the gear-wheels m and n is clearly shown in Fi 5. The arrows marked 12 represent the direction in which the disk 10 revolves, and the arrows marked 13 represent the direction in which the cam It revolves.

As the construction and arrangement of the several parts of our improved horseshoe-machine and the relation said parts bear to each other will be seen and understood by the skillful mechanic from the above description, and by reference to the accompanying drawings, we will, without further description, proceed to describe the operation of our improved horseshoennachine, which is as follows: Iron of the desired and proper size and form is fed into the machine, as indicated by the bar marked let in Fig. 2, and the revolving of the disk in will bring the long arm of the clamp y in contact with the guide J, which will press and hold the iron 14 against the die 8 until the iron is bent around the die 8, as shown in Fig. 3. At this point of the operation the catch on the end of the spring p drops into a notch made in the disk 0, as indicated in Fig. 4, and prevents the shaft D and the disk 20 from revolving until the cam iforces the lever g and vthe die 8 up to its workto wit, to cut off,

swage, and punch the nail-holes in the shoe after which the spring h will cause the lever g to fly back and the shank 5 of the press-tool 4 will strike against the lug 11 on the cam i, which will cause the press-tool to force the shoe out of the die 8 and allow it to drop on a suitable guide or chute for carrying the formed shoe off from the machine.

It will be observed that the cam 7c, by pressing down on the lug t of the feed-guide i, will move said guide down out of the way of the die 8 on lever 9 until said die has performed its office, after which the spring a will force back the guide l to the proper position for guiding the iron to the die 8 for forming a11- other shoe.

The friction-roller shown by the dotted lines marked a: in Fig. 2 is used for preventing the friction of the iron on the feeding-guide l during the process of bending it around the die 8.

In the construction and arrangement of the several parts herein described and represented we wish it clearly understood that we do not confine ourselves to any particular form or size or arrangement of said parts, as these may be varied both in form, size, and arrangement.

Having thus described the nature, construction, and operation of our improvement, what we claim as of our invention is 1. The revolving disk 20, provided with die 5 and clamp y, when used in combination with the adjustable guide J or its equivalent, as

herein described, and for the purpose set forth. 2. The lever g, provided with the swaging and punching die 8 and cutter 6, when used in combination with the revolving disk 10, die 8, clamp 3 and guide J, as herein described, and for the purpose set forth.

3. The cam t, provided with the lug 11, when used in connection with the lever g and the.
